Gentilissimi/e, vi invio un avviso di seminario, con preghiera di massima diffusione. Sede del seminario: Istituti Biologici 2, Università di Verona, strada Le Grazie 8 (VERONA). Distinti saluti, Alessandro Marcon Alessandro Marcon, PhD Unit of Epidemiology & Medical Statistics Department of Diagnostics and Public Health University of Verona Strada Le Grazie 8, 37134 Verona, Italy tel. +39 045 8027668 Avviso di SEMINARIO Lunedì 9 novembre 2015 (ore 13.00-13.45) Aula E - Istituti Biologici (Istituti Biologici 2, blocco B, secondo piano) Dr. Cosetta Minelli Senior Lecturer in Medical Statistics, National Heart and Lung Institute, Imperial College London *Mendelian randomization: * *The use of genes as instruments to strengthen causal inference in epidemiology* Mendelian randomization is an approach that uses genes as instrumental variables to derive unconfounded estimates of the effects of risk factors (e.g. biomarkers) on disease traits, and is therefore increasingly being used in epidemiology to distinguish causal from spurious associations. Since genes are randomly allocated at conception, genetic effects on a biomarker cannot be affected by classical confounding (e.g. lifestyle factors) or reverse causation (e.g. biomarker level being influenced by the presence of disease). Demonstration that a genetic variant known to modify the biomarker also modifies the disease trait represents indirect evidence of a causal biomarker-disease association. The validity of Mendelian Randomization, however, is based on instrumental variable assumptions, the most important being absence of pleiotropy. This talk will describe the approach, discuss ways to assess pleiotropy, highlight opportunities and challenges offered by available genome-wide data, and discuss its extension to the field of epigenetics (two-step epigenetic Mendelian randomization).

In this letter we consider a dynamic network with random link activation and deletion (RLAD) with non-exponential inter-event times. We study a semi-Markov random process when the inter-event times are heavy tailed Mittag-Leffler distributed, thus considerably slowing down the corresponding Markovian dynamics and study the system far from equilibrium. We derive an analytically and computationally tractable system of forward equations utilizing the Caputo derivative for the probability of having a given number of active links in the network. http://journals.aps.org/pre/abstract/10.1103/PhysRevE.92.042801 Tutti gli interessati sono invitati a partecipare. -- Federico Polito Department of Mathematics University of Torino Via Carlo Alberto, 10 10123, Torino, Italy Email: federico.polito(a)unito.it Tel: +39 011 6702937 Web: www.federicopolito.it

Politecnico di Milano - Seminari Jim Ramsay e Michelle Carey
by Laura M. Sangalli 28 Oct '15

28 Oct '15

Si avvisa che in data 6-11-2015, alle ore 10:30 precise, presso l'Aula Seminari "F. Saleri" VI piano - Dipartimento di Matematica, Politecnico di Milano, nell'ambito delle iniziative MOX, si svolgeranno i seguente seminari: ore 10:30 Jim Ramsay, McGill University, Exploring Functional Data with Dynamic Models ore 11:30 Michelle Carey, McGill University, Data2PDE: an iterative scheme for obtaining data driven estimates of the parameters of PDEs defined over complex domains Seguono gli abstracts dei due seminari. Jim Ramsay Exploring Functional Data with Dynamic Models Discrete observations of curves are often smoothed by attaching a penalty to the error sum of squares, and the most popular penalty is the integrated squared second derivative of the function that fits the data. But it has been known since the earliest days of smoothing splines that, if the linear differential operator D^2 is replaced by a more general differential operator L that annihilates most of the variation in the observed curves, then the resulting smooth has less bias and greatly reduced mean squared error. This talk will show how we can use the data to estimate such an operator. The differential equation estimated in this way is already an interesting model for the data that represents the dynamics of the processes being estimated. But, in addition to the advantages in bias and MSE, it emerges that exciting new ways of representing the data emerge that use an orthogonal basis system defined by the estimated operator. M. Carey Data2PDE: an iterative scheme for obtaining data driven estimates of the parameters of PDEs defined over complex domains Spatial data are abundant in many scientific fields, some examples include; satellite images of the earth, temperature readings from multiple weather stations and the spread of an infectious disease over a particular region. In many instances the spatial data are accompanied by mathematical models expressed in terms of partial differential equations (PDEs). These PDEs determine the theoretical aspects of the behaviour of the physical, chemical or biological phenomena considered. The parameters of the PDEs are typically unknown and must be inferred from expert knowledge of the phenomena considered. In this talk I will discuss extending the profiling with parameter cascading procedure outlined in Ramsay et al (2007) to incorporate PDE parameter estimation. Furthermore, following from Sangalli et al. (2013) the estimation procedure is extended to include nite element methods (FEMs). This allows the proposed method to account for attributes of the geometry of the physical problem such as irregular shaped domains, external and internal boundary features and strong concavities. Thus this talk introduces a methodology for data driven estimates of the parameters of PDEs dened over complex domains. Tutti gli interessati sono invitati a partecipare.

PIETRO CAPUTO - GIOVEDI 29 - TOR VERGATA - CICLO SEMINARI PASCAL

Ciclo di Seminari - Progetto ERC grant PASCAL (Probabilistic and Statistical Techniques for Cosmological Applications) Giovedi` 29 ottobre ore 15:00 Aula Dal Passo Dipartimento di Matematica Università di Roma Tor Vergata Prof. Pietro Caputo Dipartimento di Matematica e Fisica, Università Roma Tre Titolo: Dynamical phase transition in random lattice triangulations Abstract: We consider lattice triangulations, i.e., triangulations of the integer points in Euclidean plane. Our focus is on random triangulations in which a triangulation \sigma has weight \lambda^{|\sigma|}, where \lambda is a positive real parameter and |\sigma| is the total length of the edges in \sigma. Empirically, this model exhibits a phase transition at \lambda=1 (corresponding to the uniform distribution): for \lambda<1 distant edges behave essentially independently, while for \lambda>1 very large regions of aligned edges appear. We substantiate this picture as follows. For \lambda<1 sufficiently small, we show that correlations between edges decay exponentially with distance (suitably defined), and also that the Glauber dynamics, namely the local Markov chain based on flipping edges, is rapidly mixing (in time polynomial in the number of edges in the triangulation). By contrast, for \lambda>1 we show that the mixing time is exponential. For thin rectangular regions we obtain sharp mixing time bounds for all values of \lambda<1. This is joint work with F. Martinelli, A. Sinclair and A. Stauffer Tutti gli interessati sono invitati a partecipare. .

Doctoral Seminar at LUISS
by Marco Scarsini 27 Oct '15

27 Oct '15

This is to invite you to our next doctoral seminar, on Thursday, October 29th, from 13:00 to 14:00 in room 405b. The speakers is Anna Zseleva (Maastricht University). The work presented will be: Title: Zero-sum games with charges Abstract: We consider two-player zero-sum games with infinite action spaces and bounded payoff functions. The players' strategies are finitely additive probability measures, called charges. Since a strategy profile does not always induce a unique expected payoff, we distinguish two extreme attitudes of players. A player is viewed as pessimistic if he always evaluates the range of possible expected payoffs by the worst one, and a player is viewed as optimistic if he always evaluates it by the best one. This approach results in a definition of a pessimistic and an optimistic value for each player. We provide an extensive analysis of the relation between these values, and connect them to the classical values. In addition, we also examine existence of optimal strategies with respect to these values.

LUISS Seminar_28/10 Alessandro Arlotto
by Marco Scarsini 26 Oct '15

26 Oct '15

The next Research Seminar of Economics and Finance Dept. is scheduled for Wednesday, October 28th , from 2.30 p.m. to 4.00 p.m., room 205/a, viale Romania. Our guest speaker will be Prof. Alessandro Arlotto (Duke University), who will held a lecture titled “Markov Decision Problems Where Means Bound Variances” Abstract We identify a rich class of finite-horizon Markov decision problems (MDPs) for which the variance of the optimal total reward can be bounded by a simple linear function of its expected value. The class is characterized by three natural properties: reward nonnegativity and boundedness, existence of a do-nothing action, and optimal action monotonicity. These properties are commonly present and typically easy to check. Implications of the class properties and of the variance bound are illustrated by examples of MDPs from operations research, operations management, financial engineering, and combinatorial optimization.

La famiglia Cazzavillan, attraverso il Dipartimento di Economia dell'Università Ca' Foscari, ha voluto ricordare Guido bandendo una borsa di studio per poter frequentare il primo anno di un corso dottorato presso una Università di eccellenza internazionale (la borsa è rinnovabile per un anno) e una borsa di ricerca post-doc da utilizzare presso una istituzione di livello internazionale sui problemi della povertà e del sottosviluppo, temi che Guido sentiva particolarmente cari. Entrambi i bandi sono disponibili all’indirizzo: http://www.unive.it/nqcontent.cfm?a_id=193090 e si segnala che la scadenza per la borsa di dottorato è l’8 novembre 2015 mentre la scadenza per la borsa di ricerca è il 31 ottobre 2015. Si chiede cortesemente di informare dell'iniziativa giovani e studiosi che potrebbero essere interessati. Grazie per l'attenzione e un cordiale saluto, Monica -- Monica Billio Dipartimento di Economia, Università Ca' Foscari Venezia Fondamenta San Giobbe 873, 30121 Venezia Tel +39 041 2349170, Fax +39 041 2349176 E-mail billio(a)unive.it http://venus.unive.it/billio http://ideas.repec.org/e/pbi55.html http://papers.ssrn.com/sol3/cf_dev/AbsByAuth.cfm?per_id=303041

RINVIATO: Seminario Dr. Cosetta Minelli - Mendelian Randomisation - 12 ottobre 2015
by Alessandro Marcon 10 Oct '15

10 Oct '15

Gentilissimi/e, vi avviso che il seminario in oggetto è stato rimandato a data da destinarsi, a causa del grave lutto che ha colpito la nostra Sezione. Il Prof. Roberto de Marco, ordinario di Statistica presso la scuola di Medicina e Chirurgia, Università di Verona, ci ha lasciati ieri mattina. Tutti noi, orgogliosi di essere stati suoi allievi, vi diamo questo annuncio con profondo dolore. L'ultimo saluto verrà dato presso le celle dell'ospedale di Borgo Roma (Verona) lunedì 12 ottobre dalle ore 13.30 alle ore 14.30.

Seminario ROSSELL

******************************************************************* STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO ******************************************************************* Veberdi 16 Ottobre 2015 alle ore 12:00, presso l’Aula Rossa del Collegio Carlo Alberto, Moncalieri (TO), si terra' il seguente seminario: David ROSSELL (University of Warwick) CONSISTENCY OF POSTERIOR MODEL PROBABILITIES IN HIGH-DIMENSIONAL MODEL SELECTION Abstract: In recent years there has been an increasing interest in developing Bayesian formulations that remain effective in high-dimensional and non-standard problems. We focus on high-dimensional model selection problems where the number of parameters may grow with the sample size, and review results characterizing the situations under which one can hope for the posterior probability assigned to the data-generating truth to eventually converge to 1 (often termed "strong consistency"). As it turns out, under certain regularity conditions for the canonical linear model such consistency can only be achieved if the prior formulation is based on so-called non-local priors. We will review the non-local prior framework and present some recent extensions for high-dimensional estimation. Our theoretical and empirical results show that inducing model selection parsimony via non-local priors allows working with simpler models and improving prediction accuracy simultaneously. Although for simplicity we shall focus on variable selection settings, time allowing we will touch upon extensions to more complex settings such as graphical models or mixture models. Tutti gli interessati sono invitati a partecipare. Il seminario e' organizzato dalla "de Castro" Statistics Initiative (http://www.carloalberto.org/stats) in collaborazione con il Collegio Carlo Alberto. Cordiali saluti, Matteo Ruggiero --- Matteo Ruggiero University of Torino and Collegio Carlo Alberto www.matteoruggiero.it
